19723,VirtualBox 6.1.12 r139181 for Linux fails to install on Ubuntu 18.04.4 with mainline kernel 5.7.8-050708-generic,Daniel Bonner,,"Hi,
I'm using Ubuntu 18.04.4 and mainline kernel 5.7.8-050708-generic (installed with UKUU)

When installing Virtualbox:
sudo ./VirtualBox-6.1.12-139181-Linux_amd64.run

I get the following errors:
{{{

vboxdrv.sh: failed: modprobe vboxdrv failed.
}}}
I can run VirtualBox.  However, when I try to run a guest, I receive this message:
{{{
Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver is either not loaded or not set up correctly.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.
}}}
sudo /sbin/vboxconfig fails and gives the same output to the terminal as the installer.

There are no errors in /var/log/vbox-install.log and no errors in /var/log/vbox-setup.log.

The kernel modules do not work because they are installed in the wrong directory.
The installer puts them in:
{{{
/lib/modules/5.7.8/misc     (which is incorrect)
The installer also puts the follow 0 byte files which do not work in /lib/modules/5.7.8-050708-generic/misc/ (which is the correct directory for the modules):
-rw-r--r-- 1 root      0 Jul 15 20:02 vboxdrv.ko.~signed~
-rw-r--r-- 1 root      0 Jul 15 20:02 vboxnetadp.ko.~signed~
-rw-r--r-- 1 root      0 Jul 15 20:02 vboxnetflt.ko.~signed~
}}}
I can fix this by issuing these commands:
{{{
sudo rm /lib/modules/5.7.8-050708-generic/misc/vboxnetflt.ko.~signed~
sudo rm /lib/modules/5.7.8-050708-generic/misc/vboxnetadp.ko.~signed~
sudo rm /lib/modules/5.7.8-050708-generic/misc/vboxdrv.ko.~signed~ 
sudo mv /lib/modules/5.7.8/misc/* /lib/modules/5.7.8-050708-generic/misc/
sudo rm -rf /lib/modules/5.7.8
}}}
Then I reboot.

Then VirtualBox and guests run properly.",defect,closed,installer,,invalid,VirtualBox 6.1.12 installer defect Ubuntu 18.04.4 mainline kernel 5.7.8-050708-generic,,all,Linux
